These lovely little flavour cubes are for when you want something tasty alongside your water without the extra additives. Initially was drawn to this brand for its steel and glass double-walled cups, as I was looking for something that would insulate my drinks and also provide moustache protection; I then decided to get the Iced Tea and Cola flavours which I live for, especially the cola cubes. I've decided to get all other flavours to try and I've been impressed by how easy it is to use, just drop it into your bottle and you're good to go! As someone who likes their drinks on the more diluted side, I like how I can adjust the flavour by adding more water - this helps me stay hydrated throughout the day :)
